BloombergLP::bdljsn::Tokenizer::setAllowNonUtf8StringLiterals

Set the allowNonUtf8StringLiterals option to the specified value and return a non‐`const` reference to this tokenizer. If the allowNonUtf8StringLiterals value is false this tokenizer will check string literal tokens for invalid UTF‐8, enter an error mode if it encounters a string literal token that has any content that is not UTF‐8, and fail to advance to subsequent tokens until reset is called. By default, the value of the allowNonUtf8StringLiterals option is true. The behavior is undefined unless e_RELAXED == conformanceMode().
